Details
The Cubis® II Ultra-High Resolution Balances from Sartorius are precise analytical instruments used to weigh very small quantities of samples with high precision. The performance in a lab environment often deviates from instrument specifications due to varying environmental conditions and influences deriving from samples and users. The higher the resolution, the greater the relative measurement uncertainty is. Needless to say, these devices are particularly sensitive to imperfect laboratory conditions. The goal was to build a balance which is less prone to environmental effects, resulting in faster weighing workflows yet improved specifications.
